Regenerated baking-free archaized black brick and manufacturing method thereof
The invention discloses a regenerated baking-free archaized black brick and a manufacturing method thereof. The regenerated baking-free archaized black brick comprises the following raw materials in percentage by weight: 7-12% of 42.5 MPa-grade ordinary portland cement, 0-10% of II-grade fly ash, 75-80% of waste concrete blocks with the size of 0-10mm, a proper amount of pigment and a proper amount of water. The method comprises the steps of adding the waste concrete blocks and the II-grade fly ash according to a ratio, then adding a green pigment, adding a small amount of a blue pigment for multiple times, conducting stirring, adjusting the designed color, and then manufacturing the regenerated baking-free archaized black brick by using a brick machine through an excitation molding process. According to the invention, the waste concrete blocks are selected as the main material for manufacturing the regenerated baking-free archaized black brick, the colors of the waste concrete blocksand the regenerated baking-free archaized black brick are close, wastes are utilized, and lots of land resources are saved; a proper amount of II-grade fly ash is added, so that the porosity of the brick body can be reduced, and the compactness and 28-day compressive strength of the brick body are improved; the mixing amounts of the two pigments are determined by regulating, so that the brick bodycan be effectively ensured to reach the designed color; and According to the manufacturing process, the defect of CO2 gas emission caused by a firing process is avoided, a large amount of energy is saved, and the ecological environment is improved.
本发明公开了再生免烧仿古青砖其制作方法，其原材料比例为7～12％的42.5MPa级普硅水泥，0～10％的Ⅱ级粉煤灰，75～80％0～10mm的废弃混凝土块，适量的颜料，水。将废弃混凝土块和Ⅱ级粉煤灰按照比例加入后再加入绿色颜料并少量多次加入蓝色颜料进行拌制，调出设计颜色后用砖机采取激振成型工艺制作再生免烧仿古青砖。本发明选择废弃混凝土块作为制作再生免烧仿古青砖的主要材料，不仅仅二者颜色接近，而且废物利用、节省了大量的土地资源；Ⅱ级粉煤灰的适量加入可以降低砖体的空隙率，提高砖体的密实度和28天抗压强度；通过调试确定两种颜料的掺加量，可有效确保砖体达到设计的颜色；该制作工艺避免了烧制工艺带来的CO2气体排放的弊病，节省了大量能源，改善了生态环境。
